versionCode 120
versionName "1.2.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.android.support:recyclerview-v7:22.+'
compile 'com.android.support:design:22.2.1'

}
but it fails with this updated build.gradle 但它失败了这个更新的build.gradle
apply plugin: 'com.android.application'

FATAL EXCEPTION: main Process: com.mt.stackoverflow, PID: 31453 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.mt.stackoverflow/com.mt.stackoverflow.MainActivity}: java.lang.IllegalArgumentException: Target must not be null.
Any ideas how I can run the sample with the moste recent build.gradle dependencies ? 有关如何使用moste最近的build.gradle依赖项运行示例的任何想法？

The project is trying to access the ImageView in the header of the NavigationView in fragment_menu.xml in a way that is not compatible with the newer version of the support library. 该项目试图以与支持库的较新版本不兼容的方式访问fragment_menu.xml中NavigationView的标题中的ImageView 。 You can find the details in this post . 您可以在这篇文章中找到详细信息。
The ImageView is used as the target in a Picasso call and since the ImageView can no longer be found it is null and that is the cause of the IllegalArgumentException: Target must not be null error. ImageView在Picasso调用中用作target ，并且由于无法再找到ImageView因此它是null，这是IllegalArgumentException: Target must not be null的原因IllegalArgumentException: Target must not be null错误。
To fix it open the class MyMenuFragment and replace onCreateView(...) with the following: 要修复它，请打开MyMenuFragment类，并使用以下内容替换onCreateView(...) ：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_menu, container, false);
View header = ((NavigationView) view.findViewById(R.id.vNavigation)).getHeaderView(0);
ivMenuUserProfilePhoto = (ImageView) header.findViewById(R.id.ivMenuUserProfilePhoto);
setupHeader();
return setupReveal(view) ;
}
Basically you can no longer find ivMenuUserProfilePhoto directly from view . 基本上你不能再直接从view找到ivMenuUserProfilePhoto 。 You first need to get the header view from the NavigationView and then find the ImageView using the header. 首先需要从NavigationView获取标题视图，然后使用标题查找ImageView 。
